During the past 6 months, 73.2% of us households purchased sugar. assume that these expenditures are approximately normally distributed with a mean of $8.22 and a standard deviation of $1.10. 99% of the households spent less than what amount? show your work in detail.
mean = $8.22
standard deviation = $1.10
z = x – mean / standard deviation
2.33 = x – $8.22 / $1.10
2.33 x $1.10 = x - $8.22
2.563 = x - $8.22
2.563 + $8.22 = x
10.783 = x
